Corwin's Notes
=====
NGC 5216 and NGC 5218. The MCG identifications are reversed from those by all
other observers. There is no apparent reason for this in the NGC itself, and
I doubt that Vorontsov or his colleagues consulted JH's 1833 catalogue where
there is an identification error. For the record, Sir John makes his h 1635 a
"nova" while he incorrectly labels h 1636 as H II 841. Sir William's
original observation was of two objects which became H II 841 and H II 842.
Sir John got the identifications sorted out for the GC, and the NGC has them
exactly correct, too.
So, the MCG is the only catalogue which reverses the identifications. All the
other modern catalogues are correct in placing N5216 south-preceding N5218.
Steve's Notes
=====
NGC 5216
17.5" (5/23/98): smaller and fainter of pair with NGC 5218 4.0' N (Keenan's System = interacting on long exposure photos). Fairly faint, round, 1.0' diameter. The core is 15" in diameter at 280x.
